10 Established processes control all stages of manufacture to ensure quality consistent with international standards and customer requirements. Occupational health and safety as well as environmental protection are accorded prime significance and guide all aspects of manufacturing at the & BenefitsTriple-offset GeometryIn Triple-offset Butterfly Valves , the shaft is offset from the sealing surface and body centreline. Further the sealing cone is rotated away from the bore centreline to create a third offset. The Triple-offset geometry ensures that the body and disc come into contact only at the final shut-off position.
